tjout Thanks, that confirms my initial thought of waiting. Since it is very likely only a matter of weeks I think one extra year of support is a nice benefit as well.
Remember, the devs of GrapheneOS is really good at porting GOS to new devices, but it may take some days or weeks before GOS is ready on Pixel 8. After all it's a brand new device with new hardware (Tensor G3). And the devs needs to purchase the phone to be able to develop GOS on it. I hope they are funded enough that they can buy some phones to several of the team devs.
